I have found lots of beds with mine. And most of the time will use a 14 to 16ft rod to drop a Ky rig in there. Use a rubber band on the sinker. And it allows me to work the bait but not move the sinker. Do the same on crappie and bass.
Heres a shot in 6ft of water showing the beds and you can see the fish on the beds. White spot in the bed = fish
Beds next to an old road bed.
